CARRIER FOR PNEUMATIC TRANSMISSION SYST EMS.

SPECIFICATION forming part of Letters Patent No. 657,077, dated September 4, 1900.

Application filed October 1, 1898. Serial No. 692,380. (No model.)

To all whom it may concern.-

Be it known that I, BIRNEY O. BATCHELLER, a citizen of the United States of America, residing in the city and county of Philadelphia, in the State of Pennsylvania, have invented a certain new and useful Improvement in Carriers for Pneumatic Transmission Systems, of which the followingis a true and exact description, reference being had to the accom panying drawings.

My invention relates to carriers such as are used in connection with pneumatic transmission systems, and has for its object to provide a simple and eifective lock for securing the covers of the carriers in place.

I have illustrated the invention as applied to a carrier or cylinder especially adapted for insertion in the ordinary carriers forming an inner cylinder or receptacle, in which the mail or other matter is inclosed and which will hold its contents intact in case the lid of the outer or true carrier should open in transit; but it will be readily understood that myinvention is applicable also to the closure of the lids of the true carrier.

The nature of my improvements will be best understood as described in connection with the drawings, in which they are illustrated, and in which- Figure 1 is a longitudinal section of the carrier-cylinder, taken as on the line a; x of Fig. 2. Fig. 2 is an end view of the carrier, showing the lid closed and locked in position. Fig. 3 is a plan view of the lid; Fig. 4, aplan view of the locking-bar used in connection with the lid, and Fig. 5 a sectional view taken on the line 1/ y of Fig. 2.

A indicates the cylindrical body of the carrier, A indicating the edge of the cylinder at the lid end, and B a dished and flanged plate of metal, which by means of its flange B and rivets b is secured to the other end of the carrier.

0 indicates a hinge, one plate 0 of which is secured, as by rivets o, to a flattened por-.

tion A of the cylinder, while the other plate (3 of the hinge is secured, as by rivets 0 to the lid.

D is a lid-seat formed on the inside and at a short distance from the outer edge A of the cylinder and preferably made up, as shown,

of an annular band of metal riveted to the cylinder, as indicated at d.

E E, (be, are inwardly-projecting lugs secured to the open edge A of the carrier, conveniently by riveting plates of metal to it, the rivets being indicated at 6. These lugs lie over the face of the seat D and at a distance from it which is equal to the combined thicknesses of the lid and of the locking-bar, to be hereinafter described.

F is the lid, which is preferably made to fit closely on the inside of the carrier and-formed with recesses F F, &c., corresponding in size and position to the lugs E, and which permit the lid to close down upon its seat, clearing these lugs. As shown, I form the lid-plate (see Fig. 8) with a central perforation F and two lateral segmental slots F F G is a plate riveted to the front of the lid F and having a lip G, beneath which the segmental extension of the locking-bar lies, the lip serving to hold it in position and close to the top of the lid.

H is the locking-bar, which is preferably formed, as shown, with a segmental extension H, the edge of which corresponds and registers with the edge of the lid F and is formed with slots H H &c., which in one position of the bar registers with the slots F in the edge of the lid. The locking-bar is formed with a central perforation H and is secured in place on the lid by a stud or rivet I, passing through the perforations H and F, as shown, and forming a pivotal connection betweenthelidandlocking-bar. Jisahinged handle of U form with outwardly-turned ends J, which are held in place by bail-pieces J secured by rivets j to the locking-bar. Preferably one rivet in each pair is formed with an extension K, (see Fig. 5,) which passes through one of the slots F in the lid, serving to hold the locking-bar close to the face of the lid and also as a stop, which by engaging with the ends of the slot limits the motion of the locking-bar.

L is a bar riveted on the face of the lid and having a spring extension L, which lies over the top of the locking-bar and is formed with adownwardly extendinglipLiwhich engages the edge of the locking-bar and holds it in position when the bar is turned to locking position. The outer end L of the spring extension is conveniently turned up, as indicated at D, to provide a hold for the finger, a headed pin L serving to prevent the bar from being raised to an undue height.

The operation of the locking deviceis easily followed. The lid being locked on the carrier, as'shown in Figs. 1 and 2, when it is desired to open it the operator by means of the upwardly-turned flange L draws the latch L above the level of the top of the locking-bar and then taking hold of the handle J turns the locking-bar to the left until its grooves H register with the grooves F of the lid and with the lugs E on the end of the cylinder. The lid can then be opened, and when it is again desired to close it it is locked in position by simply turning the locking-bar to the right, the latch L snapping down when the locking is fully accomplished and holding the locking-bar in position until the latch is again raised by the operator.

Having now described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. A carrier for pneumatic transit-tubes having a lid-seat D situated within and at a short distance from the open end of the carrier and inwardly-projecting lugs E secured to the end of the carrier so as tooverlap the lid-seat, in combination with a lid adapted to seat itself on the'seat D inside of the lugs E, said latch having notches F in its edges to enable it to clear the lugs E, a locking-bar H centrally pivoted on the outer face of the lid and adjustable on its pivot from a position in which it clears the lugs E in opening and closing to a position in which its peripheral edges lie beneath said lugs and lock the lid in place, and a spring-catch for holding the lockingbar in locked position.

2.. A carrier for pneumatic transit-tubes having a lid-seat D situated within and at a short distance from the open end of the carrier and inwardly-projecting lugs E secured to the end of the carrier so as to overlap the lid-seat,in combination with a lid adapted to seat itself on the seat D inside of the lugs E, a locking-bar H centrally pivoted on the outer face of the lid and adjustable on its pivot from a position in which it clears the lugs E in opening and closing to a position in which its peripheral edges lie beneath said lugs and lock the lid in place, a handle J hinge-connected to the locking-bar, and a spring-catch for holding the locking-bar in locked position.

3. A carrier for pneumatic transit-tubes having a lid-seat D situated within and at a short distance from the open end of the carrier and inwardly-projecting lugs E secured to the end of the carrier so as to overlap the lid-seat in combination with a lid adapted to seat itself on the seat D inside of the lugs E, said lid having recesses F formed in its edge corresponding in position and size to the lugs E, a locking-bar and segment H H centrally pivoted on the outer face of the lid and formed with recesses H in its periphery spaced and proportioned to correspond with recesses F, said bar and segment being adjustable from a position in which its recesses register with recesses F to a position in which the tune cessed portions of its periphery lie inside of the lugs E and over recesses F and a springcatch for securing the locking-bar in its lastinentioned position.
